Gross-Up Calculator

This calculator determines gross wages before taxes and deductions are withheld given a specific take-home pay amount.

Bonus Calculator (percent method)

This calculator uses supplemental tax rates to calculate withholding on special wage payments such as bonuses. If your state does not have a special supplemental rate, you will be forwarded to the aggregate bonus calculator. This is state-by state compliant for those states who allow the aggregate method or percent method of bonus calculations.

The Hourly Paycheck Calculator

Calculates take home pay based on up to six different pay rates that you enter.
